I pulled plug #3 and took some pictures of the piston with a bore scope. It's pretty dirty in there and the piston looks like the surface of the moon, and there looks to be some loose carbon. Not sure if that is causing the detonation or if the detonation is what's knocking the carbon loose and...

I put half a tank of shell 93 in it, and it still knocks. It could be the plugs, I'm running a Champion RN11YC4 which is not a hot plug, but the 81 factory service manual recommends a "65PR4Y" which I think is an Autolite 65 plug but I can't find info online or in my 90s Autolite catalog about...

It has to be in the gas, I took the Aspen out today and once the engine warmed up it spark knocks very badly if you slowly accelerate in high gear just enough to not let the transmission kick down. And it's warmer and wetter today, 60F and rainy. There's no way a slant six should knock like that...

So after I gave up on the thermoquad and put it on my 400, I switched to a Holley Economaster for the 318. It really doesn't run any different, though it has much better cold manners. Anyway, now I'm noticing that the car is spark knocking very badly under moderate loads like would be...

I just changed the fluid and filter in my 727 today and put Motorcraft type F in it, as per the recommendation of Paul Forte from turbo action. The transmission had picked up a shudder in high gear with the converter locked up and the pump was noisy, it cleared right up after the change. Not...

The choke has been disabled, it's wired open, there's no need for a choke in this area, even in January a few pats on the gas is sufficient to keep it running. The only car I have that has a functioning choke is the Aspen. The vacuum brake works properly from my testing and I've even tried...

Timing isn't an issue, I replaced the original ESA distributor and computer with MSD and new plugs when I started driving it. It has a mechanical advance with 16 degrees at idle and about 40 maximum. I have a borescope so the next time I pull the carb I'll have a look at the valves.

Yeah, the secondaries work fine. You can floor it briefly out of gear and they roll open, but no sound. The stock jets in the carb were ludicrously lean, it would bog even when gradually tipping into the secondaries and backfire if you nailed it. I've read most of the literature out there, and...

I've been tinkering with the Thermoquad on my Gran Fury for a few months now trying to get it to perform at least comparably to my Holley 84014, and it just comes nowhere even close. I can't even get it to make the trademark moan when the air door opens. The carb is a model 9365 for a 1981 318...

Ooh, another TT4 natural suede tan Aspen. How are the seats and interior so nice? Mine have been torn to shreds since the 90s and it was never really abused. It must be the climate. It gets super hot sitting outside in the sun here.

It's that time of year again and it's super hot driving to work. The Aspen doesn't have AC, which makes it nice and roomy under the hood and the nice floor vents provide a cool breeze with the window cracked, but my Gran Fury doesn't have floor vents and it's obnoxiously hot in the summer. I...

Thanks, I ordered it and installed it, everything fits and the wipers work perfectly. Even the delay still works

If you can find one, a Holley model 4011 is an excellent spreadbore carburetor for just about any Mopar V8, I ran one on my 318 and it had extremely good cold manners, response, power, and highway fuel economy compared to the original crappy thermoquad. I'm running the same carb on a 400 HP now...

According to my 1981 parts manual, the E46 engine was essentially a run of the mill 318 with a 4 bbl intake on it. The E45 had a 2 bbl intake with some heavy duty features like double row timing chain. The E48 got all the heavy duty high performance stuff, special cam, special heads, timing...

I've seen this problem before. Some of the Edelbrock performer dual plane intakes have an inner bolt hole drilled all the way through into the runners, and if you have the bolts in the outer holes of the AVS2 the inner bolt hole is a big vacuum leak to one side of the intake, which will send...
